Susceptibility to COVID-19 Scams: The Roles of Age, Individual Difference Measures, and Scam-Related Perceptions
No full textAs the COVID-19 pandemic was unfolding, a surge in scams was registered across the globe. While COVID-19 poses higher health risks for older adults, it is unknown whether older adults are also facing higher financial risks as a result of COVID-19 scams. Here, we examined age differences in vulnerability to COVID-19 scams and individual difference measures (such as impulsivity, ad skepticism, and past experiences with fraud) that might help explain them. A lifespan sample (M = 48.03, SD = 18.56) of sixty-eight younger (18–40 years, M = 25.67, SD = 5.93), 79 middle-aged (41–64 years, M = 49.86, SD = 7.20), and 63 older adults (65–84 years, M = 69.87, SD = 4.50) recruited through Prolific completed questions and questionnaires online. In a within-subjects design, each participant responded to five COVID-19 solicitations, psychological measures, and demographic questions. Age group comparisons revealedthat older adults were marginally less likely to perceive COVID-19 solicitations as genuine than middle-aged adults were. In addition, older adults perceived significantly fewer benefits than both younger and middle-aged adults did and perceived marginally higher risks than younger adults did. Hence, older adults did not exhibit greater vulnerability to COVID-19 scams. Regardless of age, intentions to respond to COVID-19 solicitations were positively predicted by higher levels of educational attainment, being married, past fraud victimization, and higher levels of positive urgency. As expected, stronger genuineness and benefit perceptions positively predicted action intentions, whereas stronger risk perceptions negatively predicted action intentions As such, COVID-19 scam susceptibility appears to be the result of a impulse control issue that is not easilyinhibited, not even by past experiences of scam victimization
Scams in the Time of COVID-19:
No full textIn this chapter we examine some of the main approaches used by scammers and the possible consequences. We (the authors) were working on this book volume when the COVID-19 pandemic broke out and were witness to the pandemic of scams, cons, and fraud that came along with it. The Federal Trade Commission (FTC) received more than 18,000 coronavirus complaints between January 2020 and April 15, 2020 (Carrns, 2020), and Google reported an unprecedented number of scam emails, having to block over 18 million a day. In the UK, likewise, a wide range of scams have circulated trying to lure individuals via emails, false websites, phone calls, and many other techniques, leading most news outlets to raise alarm and inform the wider public. During periods of social isolation, feelings of loneliness increase and people are turning to social media and online platforms to fulfil their social needs (Le Couteur et al., 2020) as well as perform activities of daily life (e.g., banking, submission of medical forms etc.). These shifting behaviors—from face-to-face to online banking and shopping—, coupled with increased calls for donation and governmental provision of funds and tax rebates, have all created a fertile ground for scammers to take advantage of people and organizations. This was even further exacerbated by the increasing sense of confusion and uncertainty. Understanding how scammers work and lure potential victims is the first step to reducing the rate of scams and fraud under such conditions. The goal of this chapter is to play witness to this phenomenon, discuss tactics, psychological factors, and contextual factors that may be activated during times of extreme uncertainty that benefit scammers, document trends in scams that have been occurring during the COVID-19 pandemic, and also review the rapidly emerging literature produced during this time.</p
Consumers’ response to mass market scam solicitations: profiling scams and responses
No full textMass marketing scams (MMSs) impact millions of people with financial losses in the billions. Understanding what types of MMSs work is key to reducing the compliance rate. Inspired by Simon’s work, we designed an experiment to examine how four different types of MMSs impact interest in and intention to respond to solicitations. We first conducted a cluster analysis on 215 actual MMS solicitations. The analysis revealed four distinct types of solicitations: negative-cold, one-reward letters, high emotionality, high scarcity letters where the prize is mentioned often, very colorful multi-prize letters, and low emotionality, low scarcity cold letters. In a second experiment, 281 participants (recruited on MTurk) were randomly assigned to read one of the four types of solicitations. Our data revealed differences in intention to respond by sending money. Furthermore, younger (vs. older) individuals indicated a higher interest in the solicitation and higher intention to send in money and rated the solicitations as significantly more beneficial and less risky. Finally, perceptions of risks and benefits were the main driving force behind compliance beyond interest and intention to comply. In line with Simon’s ideas, our study highlights the need to examine both the environment (the types of solicitations) and the decision-maker
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
